SHUTTLE FOR EMBROIDERING-MACHINES.

Application filed November 7, 1912.

To alt whom it may concern:

Be it known that I, GUSTAV BiiiiLmz, a citizen of Switzerland, and resident of Arbon, a small town in the Canton of Thurgau, Switzerland, have invented a Shuttle for Embroidering-Machines, of which the following is a specification.

My invention has reference to certain new and useful .lIIIPI'OVQIIIGIltS in shuttles for en1- broidering machines, the said improvements being clearly illustrated in the accompanying drawing, in which:--

' Figure 1 shows a longitudinal section through the shuttle, and Fig. 2 shows a plan thereof.

The body 1 of the shuttle which is of well known construction is adapted to receive near its rounded off end and at a suitable distance from the face a pin 2 which is journaled in the side walls of the said body and serves as a pivot for a cover or lid 3 ap proximately corresponding with the shape of the body 1. This cover 3 is adapted to be secured to the pin 2 by means of a set screw 41 and provided in the usual manner with slits 5 and 6 to guide the thread. It carries in turn a tongue-shaped spring 8 the rear end of which has a slot 9 terminating in a circular perforation 10. The latter serves to receive a plate 12 having a width equal to that of the said slot 9 while the length 01' diameter of the plate, which is in the form of a disk with two opposite portions cut away, corresponds with the diameter of the perforation 10. Mounted on the plate 12 is a washer 13 the edge of which is turned downward for the purpose of pressing the spring 8 onto the lid 3. The plate 12 and the washer 13 are held in position by means of a rivet 14k or the like.

Owing to the slot 9, the spring 8 which acts as a brake, may subsequent to the turning around its pivot 14, that is, from the Specification of Letters Patent.

Patented Sept. 23, 1913.

Serial No. 730,083.

I position shown in Figs. 1 and 2 into a posi tion corresponding with that of the plate 12, (shown in dotted lines in Fig. be easily \vithd-awu from its engagement with the latter and, if desired, replaced. The spring 8 is furthernun-e bulged at a point 15, the projection thus :lormed engaging, when the spring is in normal position, with an opening 16 provided in the lid 3 and preventing accidental displacement of the said spring. In order that the braking power of the spring 8 may be adjusted, provision is made on the upper side of the lid 3 of a pivoted bolt 17 serving as a tension regulator.

The particular arrangement of the lid 3 allows of ready replacement and also of easy cleaning of same.

Having now fully described my said invention what I claim and desire to secure by Letters Patent is 1- In a shuttle for embroidering machines, the combination with a shuttle body of known construction, of a pin laterally disposed and bearing in the side walls of the shuttle body, a lid mounted on said pin, the said lid corresponding with the shape of the shuttle and having guiding slits and an opening, means to secure the lid to and allow of its detachment from the said pin, and a tongue shaped spring resting on the lid and having a projection which normally engages with the said opening in the lid and being provided at its rear end with a slot which terminates in a circular perforation, and means to regulate the tension of the spring, all as described and shown.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
